<p>将著名的问候语——“Hello World”——打印在控制台中，这个艰巨任务的actor版在<a href="http://www.typesafe.com/platform/getstarted" target="_blank">Typesafe Activator</a>中一个名为<a href="http://www.typesafe.com/activator/template/akka-sample-main-scala" target="_blank">“Akka Main in Scala”</a>的教程中有介绍。</p>
<p>这个教程展示了一个通用启动类<code>akka.Main</code>，它只需要一个命令行参数：应用主actor的类名。这个main方法会创建actor需要的底层运行环境，启动主actor，并且做好在主actor结束的时候关闭整个系统的准备。</p>
<p>另外还有一个名为<a href="http://www.typesafe.com/activator/template/hello-akka" target="_blank">Hello Akka!</a> 的 <a href="http://www.typesafe.com/platform/getstarted" target="_blank">Typesafe Activator</a>教程也是关于这一问题的，不过它更加深入的描述了Akka的基础。</p>
